The Croatian M-84D also known as M-84A5 (D) is an upgraded variant of existing M-84 tanks, originally developed in Yugoslavia, with improvements to engine, armor, armament and electronics. The M-84D is equipped with a new 1,200 hp (895 kW) engine and new RRAK ERA armour. It can carry either a Rafael Samson or a Kongsberg Protector (RWS) Remote Controlled Weapon Station, and has a new Omega ballistic computer (Slovenian Fotona-made digital ballistic computer). It has an electric cupola, giving it ability to fire at multiple targets in fast sequence, and a new SDZ defence suite protects the crew from biological, chemical and nuclear strikes. The M-84D night vision capability is provided by advanced thermal imaging sensors and cameras providing the tank with night fighting capability as well as ability to see through fog, in shade, and during a storm, i.e. greatly reduced visibility. It is equipped with the latest Racal communication suite, which now comes as standard on all new M84D and M84A4 tanks. The M-84A4 and M-84D have an operational range of 700 km and a maximum speed of 65 km/h. Improvements and new auto loader have increased efficiency by 15%, meaning 9 shells per minute instead of 8 shells per minute. (Source: Wikipedia.org, CC BY-SA)
